Display inspection test
Open clean full-screen colors, gradients, and neutral grays to inspect pixels, uniformity, discoloration, and image retention.
How this result is measured
Browser-observedUser-confirmedThe browser records the input or capability it receives; you confirm physical observations the browser cannot judge.
Set brightness manually
Choose a comfortable system brightness before starting. You may increase it during inspection, but avoid uncomfortable brightness. Browsers cannot reliably control the phone’s real display brightness.
Dead/stuck pixel inspection
Use exact solid colors to look for dots, lines, patches, or pixels that differ from their neighbors.
Gradient inspection
Look for abrupt jumps, unusual bands, patches, or uneven transitions.
Uniformity / burn-in inspection
Use neutral grays to look for tint differences, uneven brightness, retention, or burn-in-like shapes.

Viewing patterns never creates an automatic pass. Save only what you personally observed.
Privacy: No account, upload, screenshot, or display capture is used. Only your user-confirmed inspection result is stored locally.
Limitations: Browser rendering, display processing, panel technology, viewing angle, brightness, color management, compression, and accessibility settings can influence what you see.
This visual browser test cannot read individual physical panel pixels, automatically identify a dead pixel, diagnose OLED/LCD hardware, measure calibrated color accuracy or nits, or guarantee the absence of burn-in or intermittent defects.
